Extraction, huh? I already finished the x360 version but I have to buy Extraction yet! My mother gave me some games for christmas but she didn't gave me a Dead Space copy. I hope it's good.
She knew I was upset because the DAMN gamestop took a little longer to deliver my NSMBW copy, so she bought it and some other games from another store. No, I won't have my money back, unfortunatelly I will have 2 NSMBW copies but hey! I killed my neighbor playing NSMBW, I had some laughs, so I am very satisfied.
I hope you enjoy your experience with the Wii, good luck man.
